Not sure what is relevant , so here goes.
I am 50, married with children. Sexually active with my wife.
I am uncircumsised with a tight foreskin, always has been with no problems.
A couple of months ago I started getting what I can only describe as a ring of dirt around the tip of my Penis/foreskin. I shower/bathe daily and regularly clean the area with warm water. I have tried Canestan and hydrocortisone creams with no effect. Also following advice on other forums Body butter then Baby lotion (not oil).
Any suggestions how I can stop this would be appreciated.
